This allowed determination of the root-mean-square nuclear charge radii, nuclear magnetic dipole moments, nuclear electric quadrupole moments and nuclear spins of the 113-131In isotopes with high accuracy.
With a proton hole in the Z = 50 nuclear shell closure of tin and several nuclear isomer states, these measurements of the indium (Z = 49) isotope chain provided an efficient probe of the evolution of nuclear structure properties towards and at the doubly-magic nuclear shell closure of 132Sn (N = 82) - revealing unpredicted changes.
